Updated October 24, 2026. Quick answer: Line 62 of California Form 540 is the Behavioral Health Services Tax. The booklet tells you to compute it if your taxable income is more than $1,000,000, using a five line worksheet that starts from line 19. The result is entered on line 62 and is added into total tax on line 64.
What this line does
The form’s label reads “Behavioral Health Services Tax. See instructions”, and the booklet’s heading for the instruction is “Behavioral Health Services Tax”. It sits in the Other Taxes block of Form 540 Side 3, below line 61 and above line 63. This page is part of the California Form 540 line by line series.
Who it applies to
The condition is printed in one sentence: “If your taxable income is more than $1,000,000, compute the Behavioral Health Services Tax using whole dollars only:” The starting number is the one on line 19, which is covered on the California Form 540 line by line pages.
What the instructions say
| Line | What the form says |
|---|---|
| Condition | “If your taxable income is more than $1,000,000, compute the Behavioral Health Services Tax using whole dollars only:” |
| Worksheet line 1 | “Taxable income from Form 540, line 19” |
| Worksheet line 2 | Less “$(1,000,000)” |
| Worksheet line 3 | Subtotal |
| Worksheet line 4 | “Tax rate” followed by the printed rate of 1% |
| Worksheet line 5 | “Multiply line 3 by line 4. Enter this amount here and on line 62.” |
The rate is printed on worksheet line 4 as a percent. Worksheet line 3 is labelled only Subtotal.
The figures the form prints
The threshold sits in the opening sentence: “If your taxable income is more than $1,000,000”. The same figure appears as the amount worksheet line 2 subtracts, printed as the line 2 entry “$(1,000,000)”. Worksheet line 4 prints a 1% rate.
Where the result goes next
Worksheet line 5 says “Enter this amount here and on line 62.” Line 62 then feeds the total: “Add line 48, line 61, line 62, and line 63. This is your total tax.” For the state’s retirement tax picture see California retirement taxes, and for how California treats gains see does California tax capital gains.
A worked example
The booklet prints the five worksheet lines, so the arithmetic can be recomputed. This is an illustration, not a state example, using an invented taxable income. The amount is invented for the computation; your own line 19 comes from your own return.
Suppose line 1, taxable income from line 19, is $1,250,000 (invented). Line 2 subtracts $1,000,000, so line 3 is $1,250,000 minus $1,000,000 which is $250,000 (computed). Line 4 is the 1% rate. Line 5 is $250,000 times 1% which is $2,500 (computed), the amount that would go on line 62.

Common mistakes
- Running the worksheet when taxable income is not over the threshold. The instruction says “If your taxable income is more than $1,000,000, compute the Behavioral Health Services Tax”
- Starting from the wrong line. Worksheet line 1 is “Taxable income from Form 540, line 19”
- Stopping at the worksheet without entering the result. Line 5 says “Enter this amount here and on line 62.”
